Abstract

Purpose: This study aimed to conduct arthroscopic evaluation of cartilage electromechanical properties and establish their correlation with International Cartilage Repair Society (ICRS) grading scores.

Methods: In 18 patients, quantitative parameter (QP) measurements were taken on the weight-bearing surface of the medial femoral condyle. Adjacently, the same site was graded using ICRS scores (0-4). Electromechanical QPs for ICRS grades 0 to 3 were obtained during arthroscopy, while complete grade 4 injuries were assessed using femur cartilage-bone blocks from knee arthroplasty. The QP values for ICRS grades 0 to 2 were compared with grades 3 and 4 using Welch t test. The corresponding QP values were assigned to ICRS grades 0 to 4 and compared using Welch ANOVA (analysis of variance). Pearson's coefficient evaluated QP-ICRS grade relationship.

Results: Healthy grade 0 cartilage displayed a mean QP value of 10.5 (±2.8 SD, n = 4). The ICRS grade 1 and grade 2 injuries were associated with QP values of 12 (±0.7, n = 2) and 13.25 (±1.77, n = 2), respectively. The grade 3 defects had QP values of 20.43 (±4.84, n = 4), whereas complete grade 4 defects showed electromechanical values of 30.17 (±2.19, n = 6). Significant differences in QP values were observed between ICRS grades 0 to 2 (mean QP 11.56 ± 2.3, n = 8) and grades 3 and 4 (26.27 ± 6, n = 10; P < 0.0001). Pearson's correlation coefficient of 0.9 indicated a strong association between higher ICRS cartilage injury grades and elevated QP values (P < 0.0001).

Conclusion: Arthroscopic electromechanical QP assessment robustly correlates with ICRS scores. The QP values for ICRS grades 0 to 2 are significantly lower, compared with grades 3 and 4.

关节镜下人体关节软骨损伤的机电评估与 ICRS 评分相关。

目的：本研究旨在对软骨机电特性进行关节镜评估，并确定其与国际软骨修复学会（ICRS）分级评分的相关性：方法：对18名患者的股骨内侧髁负重面进行定量参数（QP）测量。同时，使用 ICRS 评分（0-4 分）对同一部位进行分级。ICRS 0 至 3 级的机电 QP 值是在关节镜检查中获得的，而完整的 4 级损伤则是使用膝关节置换术中的股软骨-骨块进行评估的。采用韦尔奇 t 检验比较了 ICRS 0 至 2 级与 3 和 4 级的 QP 值。将相应的 QP 值分配给 ICRS 0 至 4 级，并使用 Welch ANOVA（方差分析）进行比较。皮尔逊系数评估了QP与ICRS等级的关系：结果：健康的 0 级软骨的平均 QP 值为 10.5（±2.8 SD，n = 4）。ICRS 1 级和 2 级损伤的 QP 值分别为 12（±0.7，n = 2）和 13.25（±1.77，n = 2）。3 级缺损的 QP 值为 20.43（±4.84，n = 4），而完全 4 级缺损的机电值为 30.17（±2.19，n = 6）。在 ICRS 0 至 2 级（平均 QP 11.56 ± 2.3，n = 8）与 3 和 4 级（26.27 ± 6，n = 10；P < 0.0001）之间观察到 QP 值的显著差异。皮尔逊相关系数为0.9，表明ICRS软骨损伤等级越高，QP值越高，两者之间的关联性越强（P < 0.0001）：结论：关节镜机电QP评估与ICRS评分密切相关。结论：关节镜机电 QP 评估与 ICRS 评分密切相关，ICRS 0 至 2 级的 QP 值明显低于 3 和 4 级。

期刊介绍： CARTILAGE publishes articles related to the musculoskeletal system with particular attention to cartilage repair, development, function, degeneration, transplantation, and rehabilitation. The journal is a forum for the exchange of ideas for the many types of researchers and clinicians involved in cartilage biology and repair. A primary objective of CARTILAGE is to foster the cross-fertilization of the findings between clinical and basic sciences throughout the various disciplines involved in cartilage repair. The journal publishes full length original manuscripts on all types of cartilage including articular, nasal, auricular, tracheal/bronchial, and intervertebral disc fibrocartilage. Manuscripts on clinical and laboratory research are welcome. Review articles, editorials, and letters are also encouraged. The ICRS envisages CARTILAGE as a forum for the exchange of knowledge among clinicians, scientists, patients, and researchers. The International Cartilage Repair Society (ICRS) is dedicated to promotion, encouragement, and distribution of fundamental and applied research of cartilage in order to permit a better knowledge of function and dysfunction of articular cartilage and its repair.
